To all whom it may concern:

Be it known that 1, JOHN J. Part tion, a citizen of the United States, and resident of Bridgeport, in the county of Fair-field and. State of Connecticut, have invented certain new and useful Improvements in Vindow- Operating Devices, of which the following is a specification.

This invention relates to improvements in power devices for window sash operators an :fl is more especially useful when employed for manipulating a series sash arranged side by side in alignment and connected to be operated simultaneously.

An object of the invention is to provide a simply and practically constructed device of the present character having mechanism throughwhich the power is designed to be greatly multiplied.

A further object is to provide a power device including a novelly constructed housing having an oil receiving pocket whereby provision may be made for continuous lubrication of the worm and seg ment carried by the manipulating shaft oi" the power device and the operating shalt of the sash operator, respectively,'and adapted to mesh with each other when the sash. are being moved to or toward open or closed position.

Still further objects are to provide'in adevice of the type mentioned a novclly constructed segment adapted to be rigidly located upon operating shafts of varying di'ann eters without the necessity of milling'or fitting the segment upon the operating shaft, and to provide an improved chain guide capable of being swivelly arranged upon the manipulating shaft of the power device inposition to ideally perform the function for which it is intended.

With the above and other objects in view, the invention resides and consists in the construction, arrangement and combination of parts as now to be'full-y described and here inafte'r specifically claimed, it being understood that such changes in details of con. struction and arrangement of parts may be made as fall Within the spirit of the invention and within the scope of the appended claim.

In the accompanying drawing forming a part of this specification, wherein like numerals represent corresponding parts:

Fig. 1 is a front elevation of the power device;

ally hun o' This housing Serial No. 435,550..

Fig. 2 is a vertical sectional view on line 22 in Fig. 1; I Fig. 3 is a sectional plan View, on a reduced scale, of a series of windows provided with sash operators and with a power device made in accordance with the principles oi? the invention as disclosed in F igs. 1 and 2: and i Fig. at is a vertical sectional view of a modified form of the invention.

In Fig. 3 of the drawing, 5 represents a window casing and 6 a window sash pivotin the openings thereof. The window sash operating mechanismtherein shown is of a well known commercial type, and includes an operating shaft 7 to which are rig" idly secured, as indicated at 8, any desired number of arms 9 pivotally attached, as shown at 10, to preferablyv longer arms 11. having their opposite ends pivoted upon the window sash as indicated at 12. The operating shalt may be mounted adjacent to the window in any desired manner as by means of bearing brackets 13 carried by the window casing and, it will be at once apparent, when the operating shaft is rotated in its bearg it will cause the sash to swing on their pivots or hinges, either toward orfrom the window casing; that is to say, arms 9 will cause arms 11 to move toward or from the casing.

The novel power device now to he doscrib'ed and adapted to be manually actuated is for the purpose of rotating the operating shaft in either direction.

Referring more especially to Figs. 1, 2 and 3, 1a denotes a pair of ll...-Sl'lfl1)l brackets attached to the window casing in s raced relation with respect to each other. Ardjustably secured to these 'l.-shaped bra kets,

as indicated at if, are attaching lla. of av housing 17 oi pee liar constructi n; a is side w bottom walls 19 which I h preferably parallel with ear. ct..- end wall 'ofany des'red configurzb preferably of about the shape shown and consisting ot a curved portion Qfland a flat portion 21. The portion oi the housing lying closest to the window casing open, except that there is a flange 22. preferably parallel. with flat portion 21, that extends from side to side of the housing and upwardly from the bottom wall thereof to provide an oil receiving pocket 23 for a purpose to be explained. In the upper portions 01'' the side walls of the housing are arranged bearings adapted to receive operating shaft '7 of the sash operator in the manner shown, and arranged upon the sh aft and within the housiuois a ginent having teeth 26 adapted to engage a worm 27 also within the housing and preterably integral with a manipulating shaft 28 mounted in bearings 29 in portion 21 and flange 22 and having a preferably square portion 30 adapted to receive a wheel 31 raving an opening of similar shape. The outer end of the manipulating shaft is threaded, and a nut 33 is for the purpose of holding the wheel upon the squared portion of the shaft. Segment 25 is preferably constructed in the manner shown; that is, the segment is a split one. it being provided with a slit 3d extending from its opening to its circumference. Adjusting screw serves the pur pose of adjusting the size of the opening of the segment, as will be obvious, and set screw 36 is for the purpose of making the segment rigid upon the operating shaft Nut 37 upon the inner end of shaft 28 in sures the position of. the shaft in its bearings, and a chain 38 may be utilized to rotate the wheel.

The manipulating shaft is provided with a reduced cylindrical. portion 39 arranged between the squared portion and the hearing in flat portion 21 oi? the housing, and swivelly arranged upon this cylindrical portion is a hub 40 from which a pair of diverging arms il extend downwardly. The lower end of each of il is otllset to provide horizontally arranged guide members 42 having guide openings' l3 therein through which the chain is adapted to freely pass, and the guide members are spaced at proper distance from each other to prevent the chain from running off the wheel.

The method ol. operating the device is apparent. W hen the chain is manipulated to turn the wheel. in either direction, the worm will mesh with the segment to turn the operating shaft of the sash operator. By supplying the pocket or? the housing wth a small quantity ct oil, the worm, and con sequently, the saginent with which it meshes, will at all times e lubsicated= swivelly supporting the chain ride upon the manip ulating shaft, the guide members will at all times assume their proper relation to the manipulating wheel.

In Fl 4: l have disclosed a modified form of the invention in which manipulating shaft 28 disposed vertically and extends down wardly and wheel 31' fixed thereon may be positioned close to the floor to be manually turned without the use of a manipulating chain. The housing 1.7 may be similar to housing 1.7. It need, however, have but one attachilig flange 16 adapted to he supported by L-shaped bracket 14-, and it is arranged so that its wall consisting oi: curved portion 20 and flat portion 2L is longitudinally disposed, as very clearly shown. The op erating shaft of the sash operator may have hearings in side walls 18 in precisely the same manner as in the case of the device of the preferred form, and the segment 25 may be similarly constructed. An Lshaped bracket 44 secured to the casing or other support rotatably receives manipulating shaft 28' to which the wheel is rigidly secured in any desired manner, as by means of a set screw 45. The manipulating shaft is mounted in bearings 29 in flat portion 21 and flange 29/, as in the case or. the de vice of 1, 2 and 3, and the manipulating shaft is supported from the window casing by means of a suitable collar 46 carried by bracket e l. The wall consisting of: curved portion 20 and flat portion 21 in the present instance constitutes the bottom of an oil receiving pocket 23. The device of the modified vtorm operates exactly does the preferred device, except that wheel 31 is rotated without the use of a chain.

VJ hat I desire to claim is:

A power device for window sash operators, comprising a one-piece housing consisting of side walls, and a continuous integral connecting wall having one end terminating in spaced relation to an opposed portion thereof to provide an opening to the interior of the housing. said side walls and connecting wall. defining an oil containing reservoir, a manipulating worm. shalt journaled in the housing, means for rotating said shaft, a sash operating shaft journaled in said housing, a segment gear mounted on said operating shaft and meshing with said worm, and a set screw engaged through the untoothed portion of said segment with the shaft and accessible through said opening of the housing,
